Onix electronic parking brake failure

Hey, I'm having a weird problem with my 2022 Chevrolet Onix with a gasoline engine. The electronic parking brake just stopped working! The handbrake doesn't engage at all. I also have a warning light on the speedometer, and the error memory has stored a fault. I've only done 29261 km. Has anyone experienced this? Could it be a brake sensor?

Initial checks showed no blown fuses, suggesting a more complex issue. The problem was identified as a defective electric motor in the brake calliper, which was confirmed and replaced at a workshop.

It sounds like you have an electronic brake malfunction. The error code and warning light, combined with the non-functional handbrake, point to a more serious issue than just a sensor. Have you checked the fuse box for any blown fuses related to the braking system?

Thanks for the quick reply! I checked the fuses, and they all seem to be fine. What else could it be? Someone suggested it might be the motor in the brake calliper. Is that even a thing? Could that stop the whole system from working?

Yes, the electric motor in the brake calliper being defective is a likely cause for your symptoms. The electronic parking brake system relies on these motors to engage and disengage the brake. Since the fuses are okay, I recommend taking your Chevrolet Onix to a qualified workshop for a brake diagnostics. The eventual repair cost could be around 505€.

Thanks a lot for the info! I took it to the shop, and you were right – it was the electric motor in the brake calliper. They're replacing it now. I appreciate the help!
